What's your budget? Hop onto carbonknifeco / chefknifestogo / bernal cutlery (three shops in the USA I have used and trust) and start looking, any knife you buy from one of those places will be BIFL with proper care. I personally like supporting independent or smaller artisan blacksmiths, but there's some great stuff from big names as well.

If you have the budget and want a known quantity, look at the bob Kramer (super well known American blacksmith) zwilling line. Basically his designs produced to his specs by zwilling in Japan. Great western style knife with Japanese steel.
